' in the tank, these racks being sup orted uponthe brackets 5 so-that the can 0 easily lifted out of the tank when esired. The bottom of the tank slopes towards the cen- 2 and which is proter where an opening is formed which is closed by, the upper end of a hollow body ,6 which i 7 with the valve casing 8. This body may be bolted to the bottom of the tank anditis formed with. three chambers 9, 10. and 11, the ehambers 10 and 11 being in communicationwith the passages 7 and 7' and the chamber 9 is connected with the chamber 10' by a screwthre'aded bore 12 and the chamber 10 with the chamber 11 by a .screw threaded bore 13 which is of smaller diameter than the'bore 12. The chamber 11 is of larger diameter than the bore 13 and the chamber 10 is of. larger diameter than the bore 12. A stand pipe 14 has its lower end screw threaded to engage the bore 12 and a stand 'pipe" 15 has its lower end screw threaded to engage the bore 13, -the pipe 15 passing through the pipe 14 and being of much smaller diameter than said pipe 14 so s connected by the passages 7 and as to leave aspacebet'ween itself and the inner wall of said-pipe 14. The pipe 15 is of greater length than the pipe 14 withits u per end passing through a hole in the top -0 pipe 14. Sprayer arms 16 and 17 are arranged to'rotate on the pipes 14 and 15, the arms being provided w1th hollow hubs 18 and 19 for engaging said pipes, the hub 18 resting upon a shoulder 20 formed. on the .pipe 14 and the hub 19 resting upon the to of said pipe 14. Each pipe is" provided with openings 21 which liquid passing through the pipes 14 and 15 w1llenter the hubs and the arms. Each hub carries apair of arms which are diametrically opposite communicate with the i interior of the hubs so that each other and the perforations 22 in the .c

and the other pair in an opposite direction.

The outer end of each arm may be provided.

, ing by a spring with a nozzle 23. These arms are arranged below the racks for the dishes and the perforations are formed in the upper part of the arms so that the spray will be directed upwardly against the dishes and as one pair 0 arms is revolved in one direction and the other pair in an opposite direction the spray will strike all parts of the dishes to thoroughly cleanse the same. As shown, the lower end of the pipe 14 is in communication With the chamber 10 and the lower end of the pipe 15 .with the chamber 11, said chambers being connected with the valve casing, as before stated, 50 that the valve'will control the flow of water mto the stand pipes.

- The valve shell-24 is of ta ered shape, the

interior of the valve casing eing of similar shape, and said shell is held in tight connection with the interior walls or. the eas- 25. The stem 26 of the valve is connected with a handle 27 by a flexible joint 28. The shell 24 is provided with four ports 29, arranged a quarter turn from each other, which are adapted to connect the interior of the shell with the assage 7' leading to the chamber 11. he shell 24 is also provided with a pair of ports 30, diametrically opposite each other,

which are arranged to connect the interior of the shell with the passage 7 leading to the chamber 10'. The central part of the shell is provided with a large port 31 which n is assoclated with the nipples 32 and 33 on the valve casing, the nipple 33 being connected with a pipe 34 which is connected with a source of supply and the nipple 32 is connected with a pipeline 35, this pipe line being connected Wltll a pump 36 and w1th a discharge pipe 37. The inlet of the pump is connected with the chamber 9 of the body 6, as shown at 38. The pump may be operated by a motor 39, the switch for controlling the circuit of which being shown at 40. A valve 41 may be placed in the outlet end of the line 35, said valve being conpipe 37 may be provided with a suction cup 43 which'is adapted to be placed over the.

drain'of the sink 44, for instance, so that the tank may be drained by siphon action after it has been partly drained b. the

ump. Of course the exhaust pipe 37 e connected with any suitable discharge pi e.

Figure 12 shows the apparatus combined with a sink, the top 3 of the tank forming may r the drain board of the sink, the inlet pipe 34 being connected with the hot water pipe 34 of the water system and-the exhaust pi e 37 being connected with the goose neck 3% of the drain for the sink.-

1 may also connect the-pump directly with the stand pipes so that a valve is not necessary. For instance, the passages 7 of the body 6' shown in Figure 13 can be connected directly to the discharge of the pump so that as soon as the pump begins to operate water will flow through the passages into the chambers 10 and 11' and thus into the f stand pipes and through the sprayer arms.

lVhere the device is attached to the city main the valve is adjusted so that the water which is station- 1 of water has entered the tank, the valve is adjusted to connect the pump with both the passages 7 and 7' or either one of said passages and then the switchis turned to supply current to the motor. The pump will then draw the Water the tank and force it through the valve means, the passages 7 and 7 into the chamber 10 and 11 and up through the stand pipes to the sprayer arms. The water will be thrown by said arms against the dishes and then the water will drop back to the tank from which it will again be drawn by the pump so that the pump will cause the water tocirculate through the parts of the device until the dishes are thoroughly cleansed. As before stated, the valve means may be set so that the water will only pass into one of the stand pipes. \Vhen this is done one set of arms will remain stationary while the second set is revolving. \Vater can be supplied to either set by the valve means. After the dishes are washed they may be sprayed with cleansing water by setting the valve means to cbnnect the supply pipe 34 with one or both stand pipes.

Figures 8, 9 and 10 show the position of the valve core 24 to admit water from the pump into passage 7 and thence to the stand pipe 15, while Figures 14, 15 and 16 show the position of the valve core to admit water from the pump into passage 7 and thence to the standpipe 14. To admit water from the pump to both passages 7 and 7 the valve core is turned to the position shown in Figures 20, 21 and 22. To admit water from the supply pipe 34 to the passage 7 the valve core is. turned to the position shown in Figures 17, 18 and 19, to admit water from the supplypipe to passage 7 the valve from the bottom of is turned to the position shown in Figures 25. To supply water from the pipe 34 di- 43 and the drain pipe will act .to withdrawthe remaining water in the tanktherefrom. In places where a water supply is not available thetank can' be filled by hand and the pump used to circulate both the washing water and rinsinglwa-ter.

As will be seen the valve can be adjusted to cause the water from pipe 34 to pass through the pump, or the passage 7, or the passage 7 or through both passages. Thevalve means can also be adjusted to cause the pump to circulate the water through both passages or either passage and said valve means may be set to close both passages and the pipe 34 so that the pump can be used for draining the tank.

When it isdesired tocleanse the device more thoroughly the racks will be lifted out and the sprayer arms lifted ofi the. stand pipes and reversed so that the perforations point downwardly. Then when the.device is started up the spray water will strike the sides and bottom of the tank and clean the same. The stand pipes can easily be removed by unscrewing them from the body 6 so that all the parts can be thoroughly cleaned in the minimum amount of time. The arrangement of the sprayer arms will cause the water to strike all parts of the dishes so that they are thoroughly cleaned and rinsed.

It is thought from the foregoing description that the advantages-and novel features of my invention will be readily apparent.
